BetaFlight OSD Set Up (requires soldering)
Modern FC (flight controller) uses MSP connection for VTX to retrieve its telemetry data. Byte Frost has
implemented MSP to fetch the following data from FC at current release: Armed/Disarmed, Current, Voltage,
RSSI. VTX transmits these data through its data channel to VRX, and VRX display the data using its built-‐in
OSD engine.
1.
In the Betaflight Configurator, choose an available UART port number for communication between
FC and VTX. Set speed to 19200. The below screen shot shows an example of selecting UART3.
2.
Refer to your FC manual to determine where the chosen UART ports are. Hard wire the specified
UART port on the FC to TX/RX ports on VTX; i.e.
•
FC.UART3.TX to VTX.RX,
•
FC.UART3.RX to VTX.TX,
